The title says it all! John Cusack, Craig Robinson and Rob Corddry star in this raunchily funny homage to so-bad-they-are-classic 1980's movies. They play 40-something buddies who are each having trouble with life. After a particularly bad episode with one of them, they, with one of their grown nephews in tow, decide to recapture the magic of a glorious day they spent 25 years ago at a now decrepit ski resort. After many drinks, a mysterious incident sets off a chain of events with the hot tub of the title, and these four are sent back to 1986 and must actually relive the day, which is before the nephew is born. It's politically incorrect, but spot-on hilarious, quite clever and a whole lot of fun.
